What happens if you apply power to the solenoid terminal? WIS says it is a yellow wire that goes to a 42 pin connector in center of bulkhead connector ?under cowel?
If that wire gets voltage when cranking, thats good and the starter would appear to be at fault. You can get voltage from the larger battery cable connector on the starter and jump that to the solenoid terminal. Might be a bit scary under the vehicle. Danger if the vehicle wants to move. Be in neutral, and/or both wheels clear of the ground, vehcile secure on stands or lift etc.
Could be just the solenoid. Used to be able to remove and overhaul these things to cure simple mechanical problems. If problem has come and gone in the past, the main starter is probably fine. Many cities have an auto electric shops that fix things like this too.
You can measure ohms to ground on solenoid terminal too. If high or infinite ohms, the coil or leads are bad.
WIS pix implies that connector from solenoid to motor is exposed. So you can check ohms across motor to ground as well. Starter frame gets ground via contact to bell housing. You can check for zero ohms across the two.
If solenoid does click in with power, its output terminal to the motor should be battery voltage. With battery power lead to solenoid removed and insulated, and battery -ve reattached, there should be around zero ohms across main power terminals of the solenoid valve.
Note that is it -very- dangerous to work around the starter with the main battery cable energized. Tools are conductive and the spark discharge could be dangerous. The working room is very limited.
